Asseration: The magnetic flux through a loop of conducting wire of a fixed resistance changes by `Deltaphi_(B)` in a time `Deltat`. Then `Deltaphi_(B)` is proportional to the current through the loop.
Reason: `I=-(Deltaphi_(B))/(R ))`

Options

A. If both asseration and reason are true and reason is the correct explanation of assertion.
B. If both asseration and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

A

Explanation

`I=-(Deltaphi_(B))/(R )`
As `R` is constant, `IpropDeltaphi_(B).
